Abstract

A surgical implant system includes an implant body and an osseostimulative surface applied to, or used with, the implant body, the surface including a calcium sulfate (CS) compound which is a member selected from the group consisting of CS dihydrate, CS hemihydrate, anhydrous CS, and mixtures thereof. The performance and rate of resorption of the osseostimulative surface may be improved or modified through the use of a stabilizing component, a viscosity modifier, a pH modifier, or a cell growth inductive microgeometry. The system is also definable in terms of an in situ system of bone augmentation in which a bio-resorbable CS matrix, in various physical forms, from a kit is disposed about the surgical implant positioned within an osseotomy site.
